I too feel like crap lately, but my concern is I developed bad diarrhea for 5 days now and I called the doctor and they told me to use immodium. Also my appetite has decreased big time. I feel my food or liquid going down a lot more and I feel there is some type of resistance or something as if nothing goes down. I don't know what is going on. Weakness can come and go, but ne sure to take your Vitamins and be sure to drink lots of Water. I am 7 months post-op and was doing pretty well, but now I don't know. I have lost 90 pounds. I am scared to be honest and thinking to call my doctor.
